Abstract
The apparatus is an x-ray tube which generates collimated x-rays. The x-ray tube anode has an x-ray generating structure which is a single crystal, so that regardless of their locations of origin all the x-ray beams leave the structure at the same limited few angles. With the structure formed as a curve, one set of beams converges at the focal point of the curve, and with the structure flat, the beams illuminate an area with parallel, collimated, x-ray beams.
Claims12
An x-ray tube comprising:
- a means for generating an electron beam;
- and
- an anode to which the electron beam is directed, the anode comprising a base structure and an x-ray generating surface attached to the base structure, with the electron beam bombarding the surface and generating x-ray radiation, and the x-ray generating surface constructed of a material which generates collimated x-ray beams.
